Tool/software:
I'm using the TPS62932 as shown in the attached diagram. The device is working per spec except when I do the following;
I run the device for a while (can be more then 24 hours) with a Vin of 25V and I randomly remove the input voltage and then reconnect it. When I do this the device will blow out with Vin shorted to both GND and BST..
This appears to happen randomly while power cycling Vin about 1 out of 5 times and has happened on multiply boards.
With these Vin power cycles, Vin is always consistent at 25V., the load on the TPS6293 can be varying but never exceed 200mA, and as the attached schematic shows, I believe I'm using the part correctly.
So can you please help me debug this problem?
Thx
